I have painted brads and hardware with acryllic paint and will also color clear bling with markers, thanks to the great suggestions here.
Going to use some of the cool coloring page images on the internet for digi stamps. They sure have some neat ones!
I also took some small foam shapes with adhesive backing (come in little packs for crafts at the dollar stores); adhered three shapes together and adhered them to the backs of large bottle tops to make stamps. Got that idea from youtube. They make cute little background stamps, and I've been able to use milk jug tops, kitty litter jug tops, pill bottle tops etc...
Also going to try to make my own larger background stamps using foam sheets, shaped punches and wooden or acryllic blocks (also saw on youtube).
